RAILWAY-SWITCH.

sPECiFiCATioN forming part of Letters Patent No. 600,859, dated March22, 1898.

Application filed November 6 1896. Serial No. 611,238. (No model.)

To all whom t may concern..-

Be it known that I, JOHN J. DIXON, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Railway-Switches;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention has reference to a novel construction in a switch forrailways, and more particularly to devices for operating switches ofelectric and street railways.

The invention consists in the features of construction hereinafter fullydescribed and claimed.

In the accompanying drawings, forming a part of this specification,Figure l is a top plan of a switch provided with operating devicesconstructed in accordance with this invention. Fig. 2 is a sideelevation, partially in section, of said switch and operating device anda car provided with a projection for operating this device. Fig. 3 is anend elevation of the switch-operating lever and accompanying parts. Fig.4 is a side elevation of the same.

Referring now to said drawings, l indicates the rails of the track, 2the switch-rails, and 3 the tongue, which forms a section of and ispivoted to one of the rails of the main track l. The said tongue 3 ismounted upon the upper end of the rotatable pin 4., mounted in suitablebearings below the rail and preferably squared at its upper and lowerends and cylindrical in its middle portion, whereby it may be rmlyattached to the tongue and to a rod 5 below the same. Situated upon themain track at a little distance from the tongue and conveniently withina well below said track is a vibratory lever 6. This said lever 6consists of a cross-bar having upright end portions 8 and a dependingstem 9. These upright end portions or arms 8 are provided at their upperends with heads 10, that are pivoted thereto in the manner shown andextend upwardly through slots Il in the bed of the track. These slots Ilare situated at the lower end of the downwardly-inclined grooves l2 onopposite sides thereof. The lever 6 is vided with a projection 13, towhich is pivoted a rod 14, that extends upwardly and is pivoted at itsother end to the rod 5, connected with the pin 4. It will be seen fromthe foregoing description that when the vi bratory lever 6 is rocked itwill, through the intermediacy of the rods 14 and 5 and pin 4, throw theswitch-tongue 3 to one side or other to open or close the switch. Tolock the said vibratory lever, and consequently the Switchs tongue, ineither of its positions and against accidental movement, a spring boltl5 is mounted upon the top plate 16 and has a double-beveled end adaptedto engage the upper or lower edge of the cross-piece of the vibra'- torylever. This spring-bolt will be drawn back by the movement of the lever,so that while it holds it against accidental displacement it allows itto move when force is applied thereto. This switch-operating mechL anismis manipulated by a projection carried by a car, and in Fig. 2 is shownan upright movable stern 17, provided at its lower end with a shoe I8and at its upper end with a footpiece 19. A spring 20 serves to lift thesaid stem and shoe, while it is depressed by means of a foot-piece. Anoperating projection of this kind is situated at each side of the car,so that the switch can be either opened or closed by the car, it beingnoted that the operating-heads of the switch device are either elevatedor depressed as the switch is opened orclosed. i y

It is preferable to make the outer end portion of the groove inclinedupwardly, as shown in said drawings, so that the shoe iirst ridesupwardly and then downwardly to operate the switch.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination with the tongueof the switch of an upright pivot towhich said tongue is secured, a rod secured to said pivot and pinned torod 14, and rod 14 pinned to the projection .13 of the vibratory lever 6so that IOO the said vibratory lever with depending stem 9, Will throwthe tongue either Way at Will by the rocking of the vibratory lever.

2. A Vibratory lever having heads situ ated Within the path of aprojection on the oar, a switch-tongue connected with and operated bysaid lever, and a spring-bolt situated in the path of said lever.

3. The combination With the rails of a track and slots situated adjacentthereto, of a vibratory lever having pivoted heads situated Within said.slots, a cross-piece, a depending stem, and a projection upon said stem,a rod pivoted to said proj eetion and to another rod, saidlast-mentioned rod being connected with an upright pivot to which aswitch-tongue is rigidly connected.

In testimony whereof I have signed this specification in the presence oftvvo subscribing Witnesses.
